A number of unanticipitated transformations were observed when various 2,5-diphenyl-1,4-ditiin sulfones were treated with sodium azide.These include a fragmentation to give 1,2-dicyano-1,2-diphenylethene, the formation of 2,5-diphenyl-1,4-thiazine-1,1-dioxide, and the rearrangement of 3-bromo-2,5-diphenyl-1,4-dithiin-1,1-dioxide to its 2-bromo- isomer.Possible mechanism for these unusual reactions are discussed.
